technical characteristics

STD
Machine working by interpolation between the cutting tool
radius and spindle axis. The single point cutting tool generates
the profile of the valve seat through an integrated design
system, using radii and straight segments.
Machine specifically appropriate for machining of racing
engines, for engine prototyping and for valve seats of very large
diameters.
Machining capacity
from 20mm to 163mm
/ 0.78’’ to 6.42’’.
Patented lightweight
workhead :
built-in spindle motor
and triple air-float
centering system.
Minimal workhead
inertia and maximal
floatation for
unmatched centering
sensitivity.
Z and U axes digitally
controlled by standard
ISO CNC language.
Built-in hollow shaft
spindle motor, variable
speed from 0 to 3000
RPM. High machining
accuracy even at low
speed due to total
lack of mechanical
transmission.
U axis controlled by
induction motor can
reach a cutting feed
rate up to 300 mm/min.
Intake and exhaust
seats can be performed
simultaneously without
tool holder changes.
Mechanical clamping
of the work head on
the machine bed with
pneumatic clamping
jack.
Modern modular
machine bed design
for improved rigidity.
Computer enhanced
static and dynamic
characteristics provide
the latest in machining
technology.

powered
by a induction driven
brushless motor with no
backlash and minimum
temperature rise. The
whole system is only
7.2 kgs (15Lbs) and the
weight is equally divided
above and below the

The hollow spindle motor
has an integrated cooling
system that can be
activated if necessary.
The stroke of 245 mm allows the combined
machining of the seat and guide with lengths
exceeding 100mm.

Works only in application with automated CNC X-axis.
Allows an automated move of the cylinder head support
table along the Y-axis. This option means you can
machine all of your seats even if they are not in the
same alignment.
Cooling through spindle
Allows you to avoid excessive cutting heat damaging
cutting bits on the hardest seats. Improves lubricity,
increases tool life and the finish level.
Laser probing
Allows you to machine the seat automatically to the
most accurate distance from the sealing face, if the
sealing face differs from a cylinder head to another.
